Will not kill herself when she is the only card left.

When night falls, most manually-activated Villager abilities can be used again. Below is a list of abilities that can be used again each day:

Lilis excels at concealing information, as you cannot Reveal or use the abilities of any character that she kills. However, manually-activated character abilities can be used again each day, creating a sort of balance. In this way, Lilis's strength can vary wildly depending on whether or not you Reveal a manually-activated info card early on.

Beyond Lilis's ability to kill, she has no unique attributes and can otherwise be treated like a Demon version of 

. Just be mindful of the order in which you Reveal cards - anyone who Lilis kills cannot be Revealed. In order to minimise damage, if you're confident early on that someone is Evil, Executing them before you Reveal them will flip their card over without ticking towards nighttime. This can be used to mitigate the effects of Lilis's ability.

If you suspect that a Night-refreshing ability character is lying, don't kill them yet; they stop refreshing their abilities once they die, and if the character is lying, that's one possibility off the table for each ability used.

Remember to use your information abilities each day, be mindful of what could be hidden underneath characters that Lilis kills, and you should be able to fight her reasonably well.
